When the car's Bluetooth is connected but there is no sound, it could be because the phone is on silent mode or the volume is turned down to zero. It might also be due to the car's navigation system not having sound enabled or the volume being too low to hear. Another possibility is that with some car Bluetooth connections, if the car is not on the Bluetooth media audio playback interface, it will continue to play the last media audio source, resulting in no sound when playing music. Here are the specific reasons: 1. Volume: The volume on the car's navigation system or the phone is not turned on. 2. Signal interference: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function.

The day I just picked up my BYD Han, I was excited to connect my phone via Bluetooth to play music, but there was no sound, which was quite frustrating. At first, I thought my phone was broken, but it might actually be that the volume wasn’t turned up. On your phone, check if the media volume is set to the lowest; don’t forget to check the car’s audio system, as it might be muted by default. The Bluetooth pairing process can also go wrong—for example, your phone might forget to authorize media audio output, or you might have selected the wrong device during pairing. I’ve also encountered cases where the phone’s Bluetooth version was too old, and BYD’s system required a compatible update—try switching to a newer phone. The simplest solution is to re-pair: turn off the car’s infotainment system and your phone’s Bluetooth, then turn them back on and search for the connection again. If it still doesn’t work, check the media source in the car’s settings to ensure it’s set to Bluetooth and not the radio. If the problem persists, consider restarting the infotainment system or updating the vehicle’s software, as BYD sometimes releases bug-fix patches. When using Bluetooth, develop good habits: test the sound once after successful pairing to avoid any issues while driving that could affect safety.
